Can I influence what is stored in the application log when it comes to OData services?

We have a lot of "green" entries in the application log on our Gateway system.

Does every single request to an OData service through the Gateway result in an entry in the application log?

Can this somehow be changed? It seems unnecessary with all these green messages.

Also when I select the option "Only Important Logs (only Messages of Type 'Error')" in transaction /IWFND/APPS_LOG, I still get all the green messages. Is that a bug?

We are on 7.50 SP06
